comprises. a suitable valve casing, 1G, having' a )drip outlet, 17, partially controlled by a ball, 18. arranged to seat under pres- ,To all fai/0m it may concern.' A

Be it Lknown that I, FRANK V. Saoanfrr, a citizen oi the United States, residing at La (Etrange, in the county of Cook and State o't sure to close the outlet 17 except for the rellllinois, have invented certain' new and uselief afforded by drip grooves. lf), in the-seat -ful Improvements in Automatic Valveof the valve and to t'all back when water Alarm Systems, oiwhich the folloi'ving is a tlow thereto is cut oit'. Thus under no cirgmcjficatou cumslances does the ball, 18, close the drip orifice absolutely. although when the valve is under internal pressure of water flow, it reduces the drip outlet to a minimum free area, and when relieved ol water pressure it opens the outlet tlun'oughly and quickly. This drip valve is arranged in connection with a pressure pipe section, 20, running to the outlet 1i; ol the main check valve, and is also connected with a pressure pipe section, 2l, cxlemliug' up from casing 1b' in rear of the check valve ball, 18, (that is to say, on the pressure sido thereof), to communicate pressure to the alarm device generally indicated at 25. .lhe alarm device shown comprises a pressure responsive movable element, herein shown as a diaphragm, 26, "forming a movable wall of chamber 27, opened lo the pressure pipe, 2]., but otherwise closed, and said diaphragm 2G constitutingl broadly a pressare-moved element communicaling with yond the drip vali'e connection. Other sure moved elements might be used.

A. signal initiatingl instrmuentality is provided, for control by the pressure-moved part QU, preferably comprising a signal device, a retarded working train or motor therefor having' au actuating;- normally to exert its ell'ort to effect the signaling operations, but normally restrained by a dominant restrainingelement, which pri-rents its. operation and is capable of potentiatirreI its operation. This .My invention relates toumprovemcnts in automatic valve-alarm sys ems, and has for .its ,general object to provide a retarded valve alarm which will occasion a signal in the event of continued.maintenance in open position of a main automatic valve, but which will not functionally respond t'oJinomentary openings of the 'valve such tis-,occur 'as the result of Water hammer in the valvcd piping. p

ne of the salient objects of my invention is to provide an arrangement whereby the retarding instrumentality is actuated wholly mechanically, and a further object is to provide an arrangement whereby the signaling apparatus is made substantially insensible to intermittent opening' of the main valve, such as accompanies water hammer.

In the drawingsmwherein I have shown an embodiment ofi y'invention, Figure l shows a check valve drip' valve, and sigualinitiatingl ap y L ratus constituting a valve alarm system embodying my invention; Fig. 2 is a section onl line 2--2 of Fig. 1; Figi'. 3 vertical cross section of a suitable drip valve construction; Fig. et is an enlarged It'ront view of the signal-initiating apparatus; and F ig. 5 is an elevation of the .motor device.

Referring' to the drawings, 10 indicates in presit al'tcr dominant restraining element is in turn controlled by the pressure-moved part, such as the diaphragm Q6, to release said power element .from restraint when the dominant element is appropriately actuated by the pressure element; and all ot these devices are preferably housed in a suitable containing casing.

In the .specific construction 28 indicates the casing structure, preferably similar in form to a gage casing, providing binding posts, 29 and 30, 'for connection with a suitable signaling circuit, 3l, including a signal tinguisher system said valvev (the construetion of which per sc forms no part of my invention) providing a casing, 1l, ,having formed therein a seat, 12, overlain by a, cheek valve, 13, said seat having a channel therein opening to an outlet port, 14, for the eduction vof water under pressure whenever the valve .is lifted :from its seat, and the channel. is correspondingly cleared.

15 indicates in general a drip valve construction, the forml illustrated in'Fig. 3 being convenient for the embodiment of my invention, but its' specific construction per se being old. Said4 drip valve as shown the pressure pipe be-` power element part, and yet is capable of maintaining a pressure thereon as long as the main valve is opened.

While I have 'herein described in some detail a particular embodiment of my invention, which I have employed in practice and found successfully to operate, it will be apparent to those skilled in the art that numerous changes might be made in the details of construction and arrangement ot parts without departure trom the spirit ot the invention and within the scope ot' the appended claims.

What I claim is:

2. In a signal device, the combination oit a pressure-responsive devices a, dominantelement controlled thereby, a power element, means for retarding operation oi the power element in one direction, and meansassociated with said dominant element and power element for control ot' the latter by the former in the unretardcd operation thereof.

3. In a signal device, the combination of a pressure-responsive device, signaling means, an element movable to initiate said signalingfmeans, retard means for said element et'- fectiveV to retard movement thereof in one direction, andfpotentiating means ttor said movable element including' a dominant clement, controlled by said pressiire-responsive means.
